priority hub problem

A week before I set 7 notifications(5 mail and 2 text msgs) as priority. But now when I opened priority hub i.e. in BlackBerry hub the separate section priority they are vanished. I mean 2 text messages vanished from priority sections.

Now look at the second picture you will find a message named (dm - sbi card) with a red strike which is a priority indicator. Though it has priority indicator it vanished from prority hub.
